Where is the "deploy" option?!

Just bought some munzee stickers to start deploying our own, so excited when they finally came in the mail yesterday. But cant find anywhere in the app how to deploy them, wtf??! Otherwise, had been having fun with the app, though the interface looks like it was developed in the early 90s
